Polyurethane Toxic Properties and Their Effects

9/11/18

Used to enhance the strength, durability, and flexibility of a wide-range of products, polyurethane is one of the most popular substances in use today. Created during World War II as a replacement for rubber, the applications of this substance are considerable, ranging from the creation of foam cushions for bedding, couches, and chairs to floor coatings to protect wood and other materials. Unfortunately, the presence of polyurethane toxic properties has caused a reconsideration in the use of this substance.
When polyurethane is properly manufactured, the chances of being exposed to toxic properties is practically nil. This is because the toxic substances are bonded to the inert material which means that they stay in place. However, if not properly bonded or if exposed to elements that can break the bonds, then polyurethane becomes dangerous.

Potential Health Risks
While it has been widely known that polyurethane contains isocyanates, it was believed that they were only a health threat when the product was being applied or when exposed to considerable heat and fire. Extreme cases of poisoning through exposure of isocyanates, such as the infamous 1984 chemical plant disaster in India cost thousands of lives.

This is why application of polyurethane products, such as floor coating, is performed in a well-ventilated area with those present wearing masks and other protections. This limits exposure and reduces the chances that such products will cause harm. It was believed that when such products dried, the toxins became trapped inside and no longer presented a threat.

However, recent studies have shown that polyurethane products such as floor coatings for example, still release isocyanates into the atmosphere years after the product was fully dried. While the amount that is released is small, over time it can build up inside homes, offices, and facilities to cause a health threat including:

Irritation of the eyes, throat, and lungs

Nausea, vomiting, and shortness of breath

Headaches and more

Those who have respiratory diseases, such as asthma for example, along with children and the elderly are more vulnerable to the effects of the toxins present in polyurethane.

Alternative Products
The good news is that for some products that contain polyurethane, you can choose a green alternative. These provide the strength, durability, and flexibility needed without the toxins, so you can feel safer in your home or work environment. These alternative products often contain polyurethane that has the toxins removed or reduced to the point where they no longer present a threat.
Keep in mind that some alternative products contain polyurethane, but the toxins have been greatly reduced or removed. This reduces the health risk considerably, making it far less likely that you or those who live or work inside will become ill.

By choosing alternatives like Hybrid Coating Technologies that provide the same benefits while avoiding the issues of polyurethane toxic properties, you can make the right choice for your home, office, or facility. Not only will you have a safer indoor air environment, but one that is attractive to potential buyers because of its non-toxic nature.
